Application February 7, 1949, Serial No. 74,957

- 1 Claim.

This invention relates to new and useful improvements in Vises and the primary object of the present invention is to provide a vise including a pair of clamping members and embodying novel and improved gear actuating means for urging the clamping membersI into clamping engagement.

Another feature of the present invention is to provide a vise including a plurality of clamping arms, an operating means for urging the arms into clamping engagement and employing a crank rotated gear and a pitman between the gear and arms for moving the arms in selected adjusted or clamped position.

A further object of the present invention is to provide a vise having an adjustable support whereby the vise may be attached in a selected vertically inclined position.

A still further aim of the present invention is to provide a vise that is simple and practical in construction, strong" and efiicient in operation, small and compact in structure, durable and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and which includes a plurality of attachments facilitating the same to be employed in various capacities for removing and replacing springs, or supporting articles.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the present invention, certain parts being broken away for the convenience of explanation;

Figure 2 is an enlarged fragmentary, transverse vertical sectional view taken substantially on the plane of the section line 2--2 of Figure 1;

Figure 3 is an end view taken substantially in the direction of arrow 3 in Figure 1;

Figure 4; is a top plan view of Figure l; and

Figure 5 is a group, fragmentary sectional view showing the vise supporting means employed in conjunction with the present invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I30 represents a pair of side members that are joined and spaced by any suitable means.

Pivoted as at I32 between the side members I30, are the inner end portions of a pair of arms I34 the free ends of which may support a suitable type of tool or jaw.

Longitudinal slots I36 are provided in the arms I34, adjacent the free ends thereof, and receive the outer ends of links 538 which are pivoted to the arms I34 by pins or the like I40.

The side members I30 are provided with 1ongitudinal slots I42 that slidably receive the enlarged end portions I44 of a slide I46 on which the off-set eye terminals I48 of the links I38 are mounted and spaced from the side members by washers I50 (see Fig. 2).

Rotatably mounted between the side members I3!) in a gear I52 that pivotally supports an eccentrically mounted operating arm I54 the free angulated end of which is pivoted on the slide I46.

Bearings I56 fixed between the side members 139 rotatably support the smooth surfaced end portions of a worm I58 that engages the gear 552. A handle I60 applied to the worm is actuated to rotate the worm and hence the gear I52 for moving the slide I46 longitudinally and thereby opening or closing the arms I34.

Obviously, any suitable hand grip, or grips such as at I52 may be secured to the side members for handling the vise. Extending transversely between the side members I30 is a bolt having a complemental nut 83. The bolt is embraced by a spacer and passes freely through the centers of a pair of externally splined, ribbed, or toothed convex members 96 that are secured to the exterior surfaces of the side members I30. The bolt also passes through a pair of internally splined concavo-convex members 92 that are rigidly secured to or form an integral part of a pair of side supports, legs or uprights 94.

The externally splined or convex members 96 are received in the concavities of the concavoconvex members 92. By tightening the nut 88, the ribs of the members 92 will lock with the ribs of the members 96 and thereby retain the present vise either in any selected tilted position with respect to the axis of the bolt 86, or in a position in which the jaw arms extend substantially horizontally.

Having described the invention, what is claimed as new is:

A vise comprising a pair of spaced side walls, a pair of arms pivoted between said side walls and including outer ends projecting outwardly from the side walls, jaws on the outer ends of said arms, said side walls having elongated registering recesses therein, a slide received in said recesses for sliding movement, a pair of links tern inally pivoted to said slide and the outer ends of said arms, and means mounted between said side walls and operatively connected to said slide for moving the latter to effect a movement of said jaws toward each other, said slide moving means including a gear rotatably mounted between the side walls, means supported between the side walls and operatively connected to said gear for rotating the latter, and an operating arm pivoted to said slide and eccentrically pivoted to said gear.
